Way back in 2006 the manufacture introduced a new escapement that
functioned at a less frenetic 21,600 vph, but even at that time tests
had shown that the AP escapement was capable of running perfectly at
43,200 vph or 6 hertz-even without the lubrication in the pallet stones,
which would quickly dissipate at that speed anyway. The omission of
lubricant solves a difficulty which has plagued watchmakers so long as
mechanical timepieces have been known: gumming or hardening of the oil.
This fresh escapement will depend on an invention by Parisian royal
clockmaker Robert Robin (1742-1799). He created new system in 1791 that
combined the virtues of the two well-known escapements throughout,
so-called free-sprung escapement and one including energy transfer via
pallet fork and guard pin within the precursor for the modern Swiss
lever escapement as created by Thosmas Mudge in 1759.
Audemars Piguet has succeeded in securing the important things about
both systems in its new high-frequency escapement, solving the oil
problem and introducing a brand new and important aspect of the sport:
